The Doctor appears in Storm Cage but to River's horror, he is not the Doctor she fell in love with. She goes with him and is forced to face the sad truth of their backwards lives. Bad summary, but I was inspired after AGMGTW. No spoilers, just a drabble.

People credit John Watson with saving Sherlock from himself. People are often wrong. Before John, someone else saved Sherlock, and she keeps saving him. Even now. A glimpse into the Sherlock only Mrs. Hudson gets to see. One Shot.
